Senior Fullstack Engineer

Festanstellung, Vollzeit · Remote

Why us?
  • Founder-led with deep experience. You’ll work directly with a small team of founders (ex-Apple, ex-Airbnb, ex-Tulip, ex-Tourlane) and are backed by a top-tier US VC.
  • Genuine ownership. As one of our first engineers, you will fundamentally shape our product, architecture, and engineering culture. Your decisions will have a lasting impact.
  • A hard problem. This isn't a simple CRUD app or a thin wrapper around an API. If you're looking for a complex, meaningful technical challenge, this is it.
Your mission
​​​​​Our high-level goal is to automate the complex, multi-party coordination of event planning. Your immediate mission is to solve a critical and fascinating engineering problem: building the tools to capture and structure expert domain knowledge.
You won't just be chaining LLM calls. You'll be designing and building a product that allows our in-house event planning experts to systematically craft, test, and scale complex prompt chains and agentic workflows. This is a core challenge at the intersection of HCI, knowledge representation, and applied AI.
Your profile
We're looking for a pragmatic, product-minded engineer who is excited to build from the ground up.
  • Our tech stack: Typescript, React, Next.js, Tailwind; backend via Drizzle with Neon; deployment and monitoring on Vercel.
  • A seasoned full-stack engineer who thinks like a product owner. You care about the "why" and have a strong intuition for good UX. We value demonstrated skill and impact over a specific number of years.
  • Comfortable with high autonomy and navigating ambiguity. You'll be a partner in shaping the solution, not just implementing tickets from a backlog.
  • Excited by the challenge of building reliable, production-grade systems on top of LLMs. Direct experience is a plus, but a deep curiosity and willingness to learn is essential.
  • Our Stack: TypeScript, React, Next.js, Tailwind, Drizzle ORM, Neon (Serverless Postgres), Vercel.
